ELEVATING-CUSPIDOR.

Specification of Letters Patent.

Patented Aug. 8, 11916.

Application filed January 3, 1914. Serial-No. 810,230.

' vating-Cuspidors, of which the following is a specification. I

The ob ect of my inventlon 15 to provide means for elevating a cuspidorfrom a floor position to such closerelation with respect to the user asto facilitate entrance of the expectorated matter into the cuspidor.

In the sick room, and likewise in hospitals, patients frequentlyeXpectorate on the floor by reason of the fact that they are not able tocarefully dispose their heads immediately over the cuspidor. Also inhotels, very unhygienic conditions exist in the immediate vicinity of aspittoon where careless users eXpect-orate upon the floor instead ofinto the spittoon.

A further object of my invention is to provide an elevating spittoon orcuspidor which is especially serviceable in connection with dental workwhere permanent proximity of a cuspidor near the arm of a dental chairwould subject the more delicate patient to nausea, the device of myinvention being especially advantageous in View of the fact that it canbe almost instantly elevated into a position so that the patient beingin the dental chair could expectorate without having the cuspidor infull view at all times.

Other features of novelty will be more fully described in connectionwith the accompanying drawings and will be more particularly pointed outand ascertained in and by the appended claims. I

In the drawings, Figure 1 is a view in side elevation of one form of thedevice of my invention showing some of the electrical connectionsdiagrammatically. Fig. 2 is a plan view thereof.

Like characters of reference designate similar parts throughout thedifferent figures of the drawings. 1

As illustrated, 1 designates a floor line and 2 a wall of an apartmentor corridor in which the device of my invention is shown disposed. Inthe wall Imay provide any suitable form of baseboard plug structure 3whereby conductors 4: and 5 may be connected with conductors 6 and 7,leading to a source of current.

I have shown the device of my invention embodied in a suitable base orplatform 8 which may be mounted on wheels 9,, if it is desired to movethe same about. An up right 10 is mounted upon the platform or base 8and may be of the height shown if the device is to be used in connectionwith a dental chair or other operating support, or it may be of reducedheight if the device of my invention is disposed opposite a bed or chairof an ordinary construction. A cuspidor is indicated at 11 and may beprovided with a bail 12 to which elevating cords 13 may be attached, asat 14. The cords 13 extend over pulleys 15 which are journaled upon arms16 of a bracket 17 which is secured to the upright 10. The cords 13 areconnected, as at 18, to a single cord 19 which is trained over a pulley20. The pulley 20 is mounted in a bracket 21, secured to the upright 10and provided with arms 22 on the terminal ends of which a roller 23-isjournaled under which the cords 13 are trained. The cord 19 extendsdownwardly and is connected with a shaft 24 which may extend through theupright 10.

It will be readily seen that when the shaft 24 is rotated, it will windthe cord 19 thereabout and elevate the cuspidor 11.

The means for elevating the cus )idor as herein shown are of anelectrical orm although I do not wish to be limited to this particularconstruction.

I have shown an electrical motor 25, mounted upon the base 8 anddirectly connected to the shaft '24 so as to rotate the same. I v

One of the conductors, namely 5, leads to the motor 25, and therefrom at26 said conductor leads to a terminal 27. Conductor 4 leads to the pivot28 of a switch having a handle or actuating portion 29 and acircuitclosing, head 30. From 28, a wire 31 leads to an incandescentlamp 32 which is carried adjacent the bail 12 so as to illuminate thearea. immediately above the cuspidor when the'latter is used in adarkened room. Leading from lamp 32 is a conductor 33 which is connectedwith a terminal 34.

When the switch lever is in the position shown in full lines, thecircuit will be open and the cuspidor 11 will maintain, its position onthe base 8 by gravity. When it is desired to elevate the cuspidor intoconvenient accessibility to permit the user to expectorate therein, theswitch handle 29 will be moved into the dotted-line position so as toinove the head 30 into circuit-closing position with respect to switchterminals 27 and 34. This will close circuit and start the motor andalso cause the lamp 32 to glow. The motor will rotate shaft 24 and windthe cord 19 thereon thereby elevating the cuspidor 11 until it reachesthe dotted-line position shown in Fig. 1. Upward movement of thecuspidor 11 above such position will move the switch 29 into theposition shown in full lines so as to open circuit. This will stop themotor and the weight of the cuspidor 11 will cause the same to descend.again onto.

the base 8. There will be enough friction of the parts together with thedrag imparted by even an armature of the small type of motor which )Imay use, so that the cuspidor 11' will not descend too rapidly so as toobjectionably crash upon the base 8. I may however, desire to place anyform of yielding support on the base against which the im pact of thecuspidor 11 may be cushioned. A stop 35 may be provided to limitmovement of the switch lever 29 in one direction.'

It is believed that the advantages and utility of my invention will beclearly understood from the foregoing description and while I haveherein shown and described one specific form of my invention, I do notwish to be limited thereto except for such limitations as the claims mayimport.

I claim 1. In combination, an expectorant re-v ceiver, means for movingthe same toward the user, and means for illuminating an area adjacentthe receiver, said means being operable by the elevation of the receiverto facilitate use of the same substantially as described.

.2. In combination, an expectorant receiver, means for elevating thesame toward the .user, a device operated upon elevation of the receiverto a usable position for throwing out said means to permit descent bygravity of said receiver to an initial position.

3. In combination, an expectorant receiver, an upright, a driven shaftcarried by the upright, a cord-like element connected. with saidreceiver and shaft to be elevated by movement of said shaft, and meansactuceiver, an upright, a power'driven winding shaft, pulleys carried bysaid upright, a cord-like element connected with said receiver and withsaid shaft and trained about said pulleys, and means actuated by thereceiver for arresting movement of said shaft, substantially asdescribed. I

Y 5. In combination, an expectorant receiver, an electric motor providedwith a shaft, 'a cord-like element connected with the receiver and withsaid shaft for elevation of the receiver to a usable position uponwinding movement of said shaft, and a switch for said motor adapted tobe actuated by the receiver to arrest elevating movement of the latter,substantially as described.

6. In combination, a base provided with an upright, an expectorantreceiver on said base, a pulley carried by said upright, a cordconnected with said receiver and trained about said pulley, an electricmotor carried by said base and having ashaft for operation of the cord,a circuit including a motor and a switch for closing the circuit by theuser to elevate the receiver, said switch being operable by the receiverto open the circuit upon elevation of the receiver to a predeterminedheight, substantially as described.

7. In combination, a base provided with an upright, an expectorantreceiver on said base, a cord connected to said receiver, a motor shaftjournaled in said upright and connected with said cord to operate thesamev and elevate said receiver, a motor for operating said shaft, acircuit including said motor and an electric swltch foroperation by theuser to close said circuit and cause the motor to elevate said receiver,said switch being operable by the receiver to open said circuit uponelevation of the receiver to a predetermined height, substantially asdescribed.
